Jakub Konka 8e1cd69717 Implement std.fs.Dir.openFileWasi
It seems that `std.os.openZ` is too POSIX-specific, so I think it
should not be a point of entry for WASI `open` call. I figure
WASI should be treated as a separate "os" that's _not_ POSIX
especially given the incoming changes in the ephemeral snapshot.
